Subject: linux-user/sparc: Handle unimplemented flush trap
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=81f04cd34ccd3dab6c796a5fbc439a8061b04ef3;p=qemu.git

linux-user/sparc: Handle unimplemented flush trap

For sparc64, TT_UNIMP_FLUSH == TT_ILL_INSN, so this is
already handled.  For sparc32, the kernel uses SKIP_TRAP.
